SHELF RETAINING DEVICE
A shelf retainer device is disclosed that comprises a retaining panel and a plurality of mounting units, which is particularly useful to prevent items from falling from refrigerator and freezer shelves. A method of a retaining items on a shelf is also disclosed.
The present invention relates to a shelf retainer device for retaining items on a shelf of, for example, a refrigerator or freezer, to improve safety and increase storage capacity.
BACKGROUND OF THE INVENTIONHome refrigerator/freezers come in a variety of configurations. Some have the freezer section on the top, some on the bottom and some have the refrigerator and freezer sections side-by-side. Each of these configurations comes with its own advantages and disadvantages. The freezer-on-top and side-by-side refrigerator/freezers have a tendency to drop items from the shelves, especially when the shelves are overcrowded. Several factors can contribute to the overcrowding of home refrigerator/freezers. Certainly, the small size of the freezer compartment compared to the main refrigerator compartment and large family size contribute to overcrowding of the freezer. In recent years however, the increased variety of foods that are available as prepared frozen foods and the consumer trend toward bulk purchasing, and thus the need for more long-term freezer storage, have greatly exacerbated this problem.
Items piled on freezer shelves, such as those in side-by-side refrigerators, can fall out when the freezer door is opened. This can create a mess or damage the frozen food items, but more importantly, a heavy frozen food item falling from an upper shelf can damage parts of the refrigerator/freezer or cause injury to the consumer. As another consequence of this phenomenon, the consumer cannot safely and conveniently utilize the full capacity of the freezer compartment without fear of causing a frozen food avalanche when the freezer door is opened. These problems can also occur with the main refrigerator compartment.
SUMMARY OF THE INVENTIONThis invention provides a shelf retainer system that is particularly useful in refrigerators and freezers.
One embodiment of the invention provides A shelf retainer device comprising a retaining panel and a plurality of mounting units, wherein: the retaining panel comprises an open mesh material and a plurality of attachment loops, and; each of the plurality of mounting units comprises an approximately L-shaped bracket having a side plate and a front plate, from which front plate extends at least one attachment knob comprising a bulbous head that fits within one of the attachment loops.
Another embodiment provides a method of retaining items on a shelf bounded by at least two walls, which comprises: providing a retaining panel comprising an open mesh material and a plurality of attachment loops; affixing a plurality of mounting units to the at least two walls, wherein each mounting unit comprises an approximately L-shaped bracket having a side plate and a front plate, from which front plate extends at least one attachment knob comprising a bulbous head; and fitting the attachment loops over the bulbous heads of the mounting units.
Certain, non-limiting aspects of the invention can be understood with reference to the attached figures.
This invention is directed to shelf retainer devices. Particular devices of the invention are particularly useful when used in freezers and refrigerators. A specific embodiment of the invention is represented in
The mesh material 108 of the retaining panel 102 is framed by a border 106 having top, bottom, left and right sides. In one preferred embodiment, the border 106 is made of an elastomeric material, which allows the retaining panel 102 to stretch. Suitable materials for the border 106 include, but are not limited to nylon, polyamide elastomers, polyester, polyethylene, polypropylene, ethylene vinyl acetate, lycra, latex rubber, butyl rubber, nitrile rubber, polyurethane, silicone and various blends or composites thereof. The border 106 may be molded integrally with or overmolded onto the mesh material 108 of the retaining panel 102. Alternatively, the border 106 can be attached to the mesh material 108 of the retaining panel 102 by sewing, adhesive or using various fasteners. At each corner of the retaining panel 102 is a loop 110, 112 for attaching the retaining panel 102 to the mounting units 104. The attachment loops 110, 112 will preferably be made of an elastomeric material and may optionally be molded integrally with the border 106. Suitable materials for the attachment loops 110, 112 include, but are not limited to nylon, polyamide elastomers, polyester, polyethylene, polypropylene, ethylene vinyl acetate, lycra, latex rubber, butyl rubber, nitrile rubber, polyurethane, silicone and various blends or composites thereof. As shown in
In an alternate embodiment, the border 106 may be constructed as a tubular sleeve to accept a drawstring, which encircles the retaining panel 102 and forms attachment loops at each corner. Optionally, the drawstring may be elastic. A drawstring lightener may be used for convenience.
Returning again to
In an alternative embodiment, the post contains a channel having a width that accommodates one attachment loop and a depth that prevents the easy removal of that loop. Different loops can have different widths, thereby providing another means of differentiating between the top and bottom parts of a retaining panel.
As shown in
Various sizes and shapes of the shelf retainer device 100 can be provided to accommodate different sizes and styles of refrigerator/freezers. For example,
Claims
1. A shelf retainer device comprising a retaining panel and a plurality of mounting units, wherein:
- the retaining panel comprises an open mesh material and a plurality of attachment loops, and;
- each of the plurality of mounting units comprises an approximately L-shaped bracket having a side plate and a front plate, from which front plate extends at least one attachment knob comprising a bulbous head that fits within one of the attachment loops.
2. The shelf retainer device of claim 1, wherein the open mesh material is stretchable.
3. The shelf retainer device of claim 2, wherein the open mesh material is framed by a border.
4. The shelf retainer device of claim 3, wherein the attachment loops are molded integrally with or overmolded onto the border.
5. The shelf retainer device of claim 4, wherein the attachment loops are stretchable, and must be stretched to fit over the bulbous head of an attachment knob.
6. The shelf retainer device of claim 5, wherein the retaining panel has a top edge having at least one attachment loop with a first inner diameter, and a bottom edge having at least one attachment loop with a second inner diameter, wherein the second inner diameter is smaller than the first inner diameter.
7. The shelf retainer device of claim 1, wherein the retaining panel has a top edge having at least one top attachment loop and a bottom edge having at least one bottom attachment loop, wherein the top attachment loop is hook-shaped and the bottom attachment loop is stretchable and must be stretched to fit over the bulbous head of an attachment knob.
8. The shelf retainer device of claim 1, wherein the L-shaped bracket comprises one or more approximately triangular buttresses that connect the side plate and the front plate.
9. The shelf retainer device of claim 1, wherein the attachment knob comprises a post separating the bulbous head from the front plate.
